If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
If I understood you correcty, you're trying to embed a gallery into your Yola website by using custom HTML, is that right?
In this case you will probably need to provide a source from which the code can get the pictures to show in the gallery. The best solution would be to upload your pictures to your Yola File Manager (Site > File Manager). Then you can use the URLs of your pictures for your HTML code.
The URL of one of your pictures looks like this:
Replace "yourdomainname.com" by your own domain, and "yourpicture.jpg" by your own file name.
If you add folders to your File Manager and upload your pictures to folders, your URL will look like this:
Replace "yourfolder" by the name of your folder.
Please let me know if this doesn't help or you have more questions.
